iPadOS 26.0.1にアップグレードしてから、画面下部のスクロールする頁の欄が稀に少し上に持ち上がる不具合が見受けられます。アプリ内の「よくある質問→その他のご意見・ご要望」の項目をタップしてもリンク切れで不具合の報告ができないため、この場でご報告を致しました。

iPadOS 18.3へアップデートしたところ、TouchID/FaseIDが使えなくなり、PINによるロック解除しかできなくなっています。 また、ビューア上の検索機能もキーボードが表示されず、検索できなくなっています。 i文庫Sの方でも同じ不具合が発生していて、困っております。 リリース後、だいぶ経っているので難しいかもしれませんが、対応して欲しいと切に願っております。 2025/02/05 追記: バージョン 3.4.38 で問題解消されたことを確認しました。 対応感謝!

NASに書籍を多くの書籍を置いているのに、ある時期からNASにアクセスできなくなった。 簡単にNASの書籍が読めるのが便利だったのに、非常に残念です。 早く修正していただきたい。
